Abstract: The paper aims to seek new maize planting patterns to bring climatic resource into a full play in Heilongjiang. Based on meteorological data (e.g. the temperature, precipitation and t radiation data) from June to September during maize growing season and the data of corresponding maize growth periods from 2005 to 2014 in Fuyu, Heilongjiang, the temperature, radiation and precipitation data were analyzed from seven leaves stage to jointing stage, jointing stage to tasseling stage, tasseling stage to milky maturity stage and milky maturity stage to maturity stage. The results showed that: the growth period of transplanting maize was 10 days more than that of direct seeding; all growth periods of maize were 10 days ahead of schedule; the utilization rate of heat, radiation, and precipitation increased by 21%, 23%, 27%, respectively; the production potential of light-temperature increased by 47%. The transplanting maize by tray made the light, heat and water resources reconfigure in each growth period. The climate productive potential was greatly improved.
